Southwest Windpower s latest turbine, the Skystream 3.7, has a rotor diameter of about and can generate up to half an average U . S . home's energy in optimal winds.

The wind farm includes 38 Enercon E-82 wind turbines, each with two megawatt rated power, 82m rotor diameter and 79m hub height as well as a transmission line and two electrical sub-stations.
33.
History of the company started in 1980, when Danish irrigation system manufacturer Danregn, diversified into the windturbine business; its first wind turbines were machines with rotor diameters of around with generator powers of.
34.
In general, a distance of 7D ( 7 ?Rotor Diameter of the Wind Turbine ) is set between each turbine in a fully developed wind farm, but micrositing optimizes placement, particularly in hilly areas.
35.
The first turbine was a Fuhrl�nder 1500 / 77 wind turbine with an 80 meter tower and a 77 meter rotor diameter . The two completed in 2011 were General Electric wind turbines.
36.
The R-5 differed from the R-4 by having an increased rotor diameter and a new, longer fuselage for two persons in tandem, The first XR-5 of four ordered made its initial flight on 18 August 1943.
37.
Sikorsky soon developed a modified version of the R-5, the "'S-51 "', featuring a greater rotor diameter, greater carrying capacity and gross weight, and a redesigned tricycle landing gear configuration; this first flew on 16 February 1946.
38.
To control the centrifugal forces at high rotational speeds, the rotor diameter typically does not exceed 1.25 meter; the required large size of the coils is achieved by their length and so the generator is mounted horizontally.
39.
The farm consists of thirty-three 3 megawatt ( MW ) wind turbines for a total capacity of 99 MW . The turbines used are Vestas V90-3MW model, which have a rotor diameter of and sit atop an tower.
40.
The wind farm is currently a test site for some new wind turbines, notably the Mitsubishi MWT92, a 2.4 megawatt turbine with a rotor diameter larger than the wingspan of any production aircraft at 92 meters, manufactured in Japan.
